the Castle of Cloud King: A Smoke Green Dragon Book

Miles Mellow has always been happy to watch the clouds drift by, but a chance meeting with Smoke the Green Dragon sends him somewhere far beyond anything he has imagined. Wrapped in swirling green smoke, Miles rises into a brilliant kingdom of floating towers, soft white roads, and bridges stretched across an endless blue sky. Something is wrong high above the world. The Cloud King has vanished, the great cloud bridges are pulling apart, and pieces of the kingdom are beginning to drift toward the horizon. With Smoke beside him and a young weather keeper carrying a jar full of tiny winds, Miles follows a trail of storms through rolling clouds, broken pathways, and strange skies where even Smoke's magical steps do not always behave as planned. Their search leads toward a dark castle surrounded by thunder, where the truth may be very different from what anyone expects. Can Miles discover what happened to the missing king and help bring the scattered cloud kingdom together before it drifts too far apart?
